Lesson Objectives Lesson Competency (Level 1-3) Proficiency Mastery (Level 7-9) 1 To understand the different properties of 3D Shapes. To be able to state the basic properties of 3D shapes. To apply this knowledge to identifying shapes by their properties.

How many different facts can you say about the shape? A 3D shape is shown below... How many different facts can you say about the shape?

The name of the shape. The number of faces it has The name of the shape. The number of faces it has. The number of edges it has. The number of corners it has – the mathematical name for this is vertices.

We are now going to find these characteristics for a number of 3D shapes…

Name: No. of Faces: No. of Edges: No. of Vertices: Cuboid 6 12 8

Name: No. of Faces: No. of Edges: No. of Vertices: Cube 6 12 8

Name: No. of Faces: No. of Edges: No. of Vertices: Triangular Prism 5 9 6

Name: No. of Faces: No. of Edges: No. of Vertices: Cylinder 3 2

Name: No. of Faces: No. of Edges: No. of Vertices: Sphere 1

Name: No. of Faces: No. of Edges: No. of Vertices: Cone 2 1

Name: No. of Faces: No. of Edges: No. of Vertices: Square Based Pyramid 5 8

Triangular Based Pyramid Name: No. of Faces: No. of Edges: No. of Vertices: Triangular Based Pyramid 4 6

3D Shape Game I will give you properties and using the shapes we have just found, you need to use a process of elimination to state the shape on your whiteboard. First correct board up wins. You need to be able to justify your answer (no guessing).

Shape 1 I have 5 faces. I have 9 edges. I have 6 vertices. I am a triangular prism!

Shape 2 I have 6 faces. I have 8 vertices. I have 12 equal edges. I am a cube!

Shape 3 I have 5 faces. I have 5 vertices. I have 8 edges. I am a square based pyramid!
